Cassava (Manihot esculenta Crantz) native starch was treated with pyroconversion and enzymatic hydrolysis to produce a pyrodextrin and an enzyme-resistant maltodextrin. Some nutritional characteristics were quantified for both compounds. Pyroconversion was done using a 160:1 (p/v) starch:HCl ratio, 90 °C temperature and 3 h reaction time. The resulting pyrodextrin contained 46.21% indigestible starch and 78.86% dietary fiber. Thermostable α-amylase (0.01%) was used to hydrolyze the pyrodextrin at 95 °C for 5 min...

Aldrin and its metabolite dieldrin are persistent organic pollutants that contaminate soil in many parts of the world. Given the potential hazards associated with these pollutants, an efficient degradation method is required. In this study, we investigated the ability of Pleurotus ostreatus to transform aldrin as well as dieldrin in pure liquid cultures. This fungus completely eliminated aldrin in potato dextrose broth (PDB) medium during a 14-day incubation period. Dieldrin was detected as the main metabolite, and 9-hydroxylaldrin and 9-hydroxyldieldrin were less abundant metabolites...

The prevalence of fungi in the respiratory tract of cystic fibrosis (CF) patients has risen. However, fungal surveillance is not routinely performed in most clinical centers in the United States, which may lead to an underestimation of the true prevalence of the problem. We conducted a prospective study comparing fungal detection rates for clinically important fungi (CIF) defined as Aspergillus species, Scedosporium species, Trichosporon species, and Exophiala dermatitidis in CF sputum using standard bacterial culture media and selective-fungal culture media, including Sabouraud dextrose agar with gentamicin (SDA), inhibitory mold agar (IMA), and brain-heart infusion agar (BHI) with chloramphenicol and gentamicin...

An approximately 10-yr-old, captive-born female toco toucan ( Ramphastos toco ) was presented due to an acute onset of depression and apathy. On visual and physical examination, it showed an abnormal posture and dehydration, respectively. Serum biochemistry revealed hyperuricemia (39.4 mg/dl) and elevated glutamic oxaloacetic transaminase (GOT; 1,050 U/L). Radiographs demonstrated an enlargement of the cardiac silhouette. The bird died 7 days after presentation, despite treatment with enrofloxacin, allopurinol, a preparation of hepatorenal protectors, and complex B vitamins with dextrose...

BACKGROUND: Insulin dysregulation, obesity, and exposure to high-non structural carbohydrate (NSC) forage are risk factors for equine metabolic syndrome (EMS)-associated laminitis (EMSAL); high systemic insulin concentrations in EMSAL are proposed to induce cellular dysregulation in the digital lamellae through activation of the IGF-1 receptor. OBJECTIVES: To use a dietary challenge model (DCM) and a euglycemic hyperinsulinemic clamp (EHC) model to assess lamellar growth factor-related signaling...

To date, only one case of post-traumatic endophthalmitis caused by Scedosporium dehoogii has been reported, but its contamination or colonization might not be precluded due to the absence of pathogenic isolation and/or pathological examination. We report the first case to our knowledge of S. dehoogii-induced subcutaneous scedosporiosis in a psoriatic patient. A 58-year-old man with 5-year history of psoriasis vulgaris and immunosuppressant therapy developed pyrexia and multiple subcutaneous abscesses on both knees...

Eucalyptus leaf blight caused by Calonectria spp. is a serious disease in Eucalyptus seedling and plantations. However, the molecular mechanisms of the infection process and pathogenesis of Calonectria to Eucalyptus is not well-studied. In this study, we analyzed the transcriptomes of C. pseudoreteaudii at three stages of Eucalyptus leaf infection, and in mycelium grown in potato dextrose broth using Illumina RNA-Seq technology. We identified 161 differentially expressed genes between C. pseudoreteaudii from leaf and mycelium grown in potato dextrose broth...

Early innovations in the delivery of peritoneal dialysis (PD) markedly improved its acceptability and lowered peritonitis rates. The standard osmotic agent was, and continues to be dextrose, an agent that is not ideal as it is readily absorbed. The development of icodextrin-containing dialysis fluid has allowed a long dwell time to provide more effective ultrafiltration. The development of a smaller, more easily used automated cycler, led to an increase in the proportion of patients on the cycler as opposed to CAPD...

The patient is a 1-week-old boy born at 37+2 weeks' gestational age through spontaneous vaginal delivery. The pregnancy was complicated by maternal gestational diabetes mellitus and pre-eclampsia. The Apgar score was 9 at both 1 minute and 5 minutes after birth. Because of hypoglycemia at delivery that required IV dextrose, he was admitted to the local neonatal intensive care unit. His blood glucose levels quickly stabilized, dextrose administration was discontinued, and the patient began breast-feeding. On day 2 of life, the patient began having intermittent oxygen desaturation, with oxygen saturation as measured by pulse oximetry down to 70% while sleeping; he was transferred to a tertiary-care NICU for further management...

Fungal endophytes are microorganisms that are well-known for producing a diverse array of secondary metabolites. Recent studies have uncovered the bioprospecting potential of several plant endophytic fungi. Here, we demonstrate the presence of highly bioactive fungal endophytic species in Aquilaria subintegra, a fragrant wood plant collected from Thailand. Thirty-three fungal endophytic strains were isolated and further identified to genus level based on morphological characteristics. These genera included Colletotrichum, Pestalotiopsis, Fusarium, Russula, Arthrinium, Diaporthe and Cladosporium...

OBJECTIVE: Plasma acts as a good indicator of oxidative stress in blood. L-carnitine is an antioxidant that reduces metabolic stress in cells, thereby providing a protective effect against oxidative stress. L-carnitine as an additive in storage has not been explored. Thus, this study attempts to analyze the role of L-carnitine in blood storage solution, Citrate Phosphate Dextrose Adenine (CPDA)-1 through oxidative stress (OS) markers - antioxidant enzymes, lipid peroxidation and protein oxidation...

OBJECTIVE/BACKGROUND: Tuberculosis (TB) continues to be a major public health problem worldwide. This is especially true in Northern Iran, which has high TB prevalence. The chronic nature of this disease is further exacerbated if it is accompanied by fungal infection, which usually remains undiagnosed and thus untreated. Thus, mycotic infections add fatal dimensions to pulmonary TB. Our objective was to determine the prevalence of invasive forms of fungal elements in sputum samples collected from patients with pulmonary TB at a reference laboratory in Ghaemshahr, Northern Iran, during the past 10years...

We describe the design, microfabrication, and testing of a microfluidic device for separation of cancer cells based on dielectrophoresis. Cancer cells, specifically Green fluorescent protein-labeled MDA-MB-231, are successfully separated from a heterogeneous mixture of the same and normal blood cells. MDA-MB-231 cancer cells are separated with an accuracy that enables precise detection and counting of circulating tumor cells present among normal blood cells. The separation is performed using a set of planar interdigitated transducer electrodes that are deposited on the surface of a glass wafer and slightly protrude into the separation microchannel at one side...
